The UN aviation agency has voiced grave concerns over North Korea's recent jamming of GPS navigation signals and called for measures to prevent a recurrence, the South Korean foreign ministry said Monday.

During its latest council session held in Montreal, Canada, from March 10 to April 4, the International Civil Aviation Organization (ICAO) adopted a decision against North Korea's GPS signal jamming, the ministry said in a press release.

The agency also decided to send a letter, under the council president's name, to inform North Korea of the decision's adoption.

The decision was made in response to a proposal by the South Korean government to the ICAO council, following North Korea's latest GPS jamming activities from October last year to mid-February, which affected thousands of flights across more than 20 countries and regions, according to the ministry.

In the decision, the ICAO expressed grave concerns over GPS signal jamming by North Korea, urged the country to comply with relevant international law and demanded that it guarantee the prevention of a recurrence.

In June last year, the ICAO adopted a similar decision, identifying North Korea as responsible for GPS jamming activities for the first time.

"While continuing to monitor North Korea's moves, the government plans to make continued efforts with the international community to ensure concerted action can be taken against its provocations, such as GPS signal jamming," the ministry said.
